摘要
Abstract
In recent years,PT-symmetric non-hermitian systems have received widespread attention from researchers in various fields due to their unique physical properties.In the teaching of quantum mechanics,it is necessary to properly introduce relevant research progress in addition to elucidating the basic concepts and physical images of quantum mechanics.It was studied of the impacts of the PT-symmetric potentialsλ(ix)kon the energy spectra of one-dimensional linear harmonic oscillator systems.By solving the energy spectra with the help of perturbation theory,and it is find that this potential plays special roles changing the energy spectra.Namely,the value of the energy correction fluctuates around its original value following the change ofk,as a result,the energy level overlap can be observed whenλis high enough.It can be believed that these results are helpful in understanding the basis and the frontier knowledge of quantum mechanics.关键词
